A method, wireless device and network node for performing sounding reference signal (SRS) transmission. According to one aspect a method includes receiving a definition of one or more SRS resource sets to be configured, comprising at least one SRS transmission setting. The method further includes receiving an indication of a selected SRS resource set to use for a SRS transmission, from the one or more configured SRS resource sets and determining a precoding configuration for the SRS transmission based on the selected SRS resource set and the at least one SRS transmission setting. The method also includes transmitting a SRS according to the determined precoding configuration.
Legal claims defining the scope of protection, as filed with the USPTO.
3. The method of claim 1, wherein the SRS transmission is an aperiodic transmission.
6. The wireless device of claim 4, wherein the SRS transmission is an aperiodic transmission.
8. The method of claim 7, wherein the SRS transmission comprises reciprocity-based precoding for the SRS transmission.
9. The method of claim 7, wherein the selected SRS resource comprises an association to a downlink reference signal (DL RS) and the SRS transmission comprises reciprocity-based precoding based on the associated DL RS.
10. The method of claim 7, wherein the SRS transmission is an aperiodic transmission.
12. The network node of claim 11, wherein SRS transmission comprises reciprocity-based precoding for the SRS transmission.
13. The network node of claim 11, wherein the selected SRS resource comprises an association to a downlink (DL) reference signal (RS) and the SRS transmission comprises reciprocity-based precoding based on the associated DL RS.
14. The network node of claim 11, wherein the SRS transmission is an aperiodic transmission.
15. A non-transitory computer readable medium storing instructions, which, when executed by processing circuitry of a wireless device, cause the wireless device to perform the method of claim 1.
16. A non-transitory computer readable medium storing instructions, which, when executed by processing circuitry of a network node, cause the network node to perform the method of claim 7.
